The High court ruled in Samsung's favour saying "the argument from Apple's lawyers had insufficient prospects of success". Samsung has said that the injunction should never have been granted in the first place. Apple had not issued a statement at the time of submission.
According to Slashgear Apple has been requested to pay Samsung's legal costs.
Given that the High court is the highest court in Australia, Apple has no chance of an appeal. Samsung is free to begin distribution of the Galaxy Tab 10.1 in Australia.
